Email validation in Marketo through Javascript

Hi Community!


We've been finding that unfortunately Marketo forms have pretty crappy email validation on them as default. Using the "Email" field means that a user is only required to enter an email with an "@" symbol - they don't need a period "." This means we get a bunch of junk emails that fail validation in our other systems.


Here's the code my developer gave me to solve this:



  MktoForms2.loadForm("//", "110-AIL-152", 1330, function(form){


        // Get the values

        var vals = form.vals();

        var re = new RegExp(/^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i);








          var emailElem = form.getFormElem().find("#Email");

          form.showErrorMessage("Please enter a valid email format", emailElem);






If I was using a "self-guided" landing page, I know how to implement this - simply create a HTML element and drop this script in the HTML code section. But with a guided landing page, it doesn't seem to work.


I've tried two ways - dumping it at the bottom of the raw code (after "editing draft" on my template), below where the other scripts are, and secondly, dropping it into a section via the landing page editor (much like I would with a "self-guided" page). Neither seems to work.


Any ideas? Is there an easier way to do this? I know you can "mask input" with fields in Marketo forms - is this a better way of doing it? Will there be disadvantages if I use this field type instead of "Email" field type?


Thanks in advance!
